Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof construction technology, and more specifically, to a waterproof roof repair structure for a pharmaceutical factory production workshop. Background Technology
[0002] Old factory buildings are constantly exposed to wind, sun, and rain, causing their roof waterproofing to deteriorate. To ensure waterproofing performance, the roof's cement layer is often scraped off and re-waterproofed. This method damages the cement layer, affecting the building's overall structure, and the resulting dust can negatively impact the factory environment, especially in areas with stringent production requirements, such as pharmaceutical workshops. Furthermore, in pharmaceutical factories, equipment often sits on the roof; damaging the cement layer necessitates moving the equipment, requiring readjustment, and rendering it unusable immediately after repair, leading to significant production delays. Therefore, this method of repairing the roof by damaging the cement layer is unsuitable for waterproofing repairs in situations like those in pharmaceutical factories.
[0003] Therefore, a roof structure that is easy to repair and whose construction process does not affect the normal use of the factory is particularly necessary. Utility Model Content

[0029] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0031] This utility model embodiment provides a waterproof roof repair structure for a pharmaceutical factory production workshop, such as... Figure 1-4As shown, it includes a roof body layer 100 and a waterproof smoothing layer 200, a thermal insulation layer 300 and a waterproof layer 400 sequentially disposed on the surface of the roof body layer 100. The thermal insulation layer 300 is fixed to the roof body layer 100 by a fixing component 500.
[0032] The fixing component 500 includes a cover 510 that abuts against the upper surface of the insulation layer 300, a fixing rod 520 whose top end is connected to the cover, and a limiting member 530 provided on the top of the fixing rod to prevent the fixing rod 520 from detaching from the cover 510. The cover 510 is provided with a fixing hole 540 for inserting the fixing rod 520, and the bottom of the fixing rod 520 is located inside the roof body layer 100.
[0033] The waterproof roof repair structure for the pharmaceutical production workshop in this embodiment of the present invention is formed on the roof body layer 100. Specifically, the roof body can be the roof, wall, or other parts to be repaired.
[0034] In this embodiment of the utility model, the waterproof leveling layer 200 can be repaired by using waterproof adhesive to repair defects such as loose, honeycomb-like ground and mortar surface at the location to be repaired, and then a layer of waterproof adhesive is brushed on to improve the waterproofing ability, while keeping the surface flat and clean. Compared with using cement or other materials to level the surface, this method helps to reduce the roof load and improve the waterproofing performance of the waterproof roof repair structure in the pharmaceutical production workshop.
[0035] In this embodiment of the invention, the insulation layer 300 is made of a material with good heat insulation performance, which helps to reduce heat exchange between the inside and outside of the factory building, enhances the building's heat insulation capacity, and at the same time can isolate the damage of ultraviolet rays from sunlight to the waterproof plaster layer 200. Because the insulation material of the insulation layer 300 is easily deformed under pressure, if screws are used for fixing, the through holes on the insulation layer 300 for screw insertion will gradually increase in number as the screws interact with each other, thus increasing the gap between the screws and the through holes. Simultaneously, since areas such as the factory roof require regular maintenance, personnel may pass through. Because the insulation layer 300 is relatively soft, it will indent under human pressure, so the pressure will primarily be borne by the screws. Since the top area of the screws is relatively small, the pressure between the screws and the waterproof layer 400 becomes excessive when personnel pass through, making the waterproof layer 400 easily damaged. In this situation, external water may seep through the damaged waterproof layer 400 and the gap between the insulation layer 300 and the screws into the waterproof plaster layer 200. Once the waterproof plaster layer 200 is damaged, leakage is likely to occur. Therefore, in this embodiment of the invention, a combination of a cover 510, a fixing rod 520, and a limiting member 530 is used to fix the insulation layer 300. On one hand, the cover 510 clamps the insulation layer 300 between the waterproofing and smoothing layer and the cover 510, ensuring a tight fit between the fixing rod 520 and the insulation layer 300 without gaps. On the other hand, in this embodiment of the invention, the area of the cover can be 32 cm². 2 As a result of the presence of the cover 510, even when someone passes by, the area of the cover 510 is larger than the area of the top of the screw, which allows the pressure between the cover 510 and the waterproof layer 400 to be dispersed to a certain extent. This makes the waterproof layer 400 less susceptible to wear and damage, which helps to extend the lifespan of the waterproof layer 400 and, consequently, the service life of the waterproof roof repair structure in the pharmaceutical factory production workshop.
[0036] The waterproof roof repair structure for pharmaceutical production workshops according to this utility model can be constructed without damaging the roof cement layer or affecting the normal use of the factory building. It has good waterproof performance and a long service life, and is easy to maintain.
[0037] In optional embodiments, such as Figure 2-4 As shown, a recessed groove 550 is provided in the middle of the cover 510. The bottom of the recessed groove 550 is in contact with the insulation layer 300. The fixing hole 540 is provided at the bottom of the recessed groove 550. The opening of the recessed groove 550 abuts against the limiting member 530 and the limiting member 530 covers the opening of the recessed groove 550.
[0038] The bottom of the sink 550 is in close contact with the insulation layer 300, which increases the contact area between the cover 510 and the insulation layer 300. This helps to disperse pressure and reduce the probability of damage to the insulation layer 300 at the pressure concentration point due to excessive pressure concentration.
[0039] The sinking channel 550 is located outside the limiting member, and the limiting member can cover the sinking channel 550, so that even if water passes through the top of the limiting member 530, it will preferentially flow along the limiting member 530 through the top surface of the cover 510 to the insulation layer 300, and will not preferentially enter the sinking channel 550. This is beneficial to improving the waterproof effect of the waterproof roof repair structure of the pharmaceutical production workshop. It should be noted that the top of the limiting member can be a flat surface or a slightly curved surface.
[0040] In optional embodiments, such as Figure 4 As shown, along the direction from the recessed groove 550 to the edge of the cover 510, the cover 510 gradually tilts towards the roof body.
[0041] In this embodiment of the utility model, the card cover 510 is arched in the middle and the edges gradually slope downward. On the one hand, it can play a guiding role to prevent water from entering the sink 550 and contacting the waterproof smoothing layer 200 through the fixing hole 540; on the other hand, when the card cover 510 is fixed and then subjected to pressure, there will be a squeezing force towards the middle of the fixing hole 540 to prevent the fixing hole 540 from becoming larger.
[0042] It should be noted that, since the insulation layer 300 material has a certain degree of deformability, in this embodiment of the utility model, the cover 510 can be "embedded" into the upper surface of the insulation layer 300 after being fixed, so that the fixing component 500 will not protrude from the insulation layer 300, thus avoiding friction between the fixing component 500 and the waterproof layer 400, which would shorten the life of the waterproof layer 400.
[0043] In an optional embodiment, the fixing component 500 includes a clip cover 510 and a self-tapping screw that passes through the fixing hole 540 and has its tip located within the roof body layer 100.
[0044] In this embodiment, the self-tapping screw is equivalent to a combination of the fixing rod 520 and the limiting member 530. Using existing parts helps to improve repair efficiency.
[0045] In an optional embodiment, a sealing gasket is provided between the self-tapping screw and the fixing hole 540;
[0046] Alternatively, the self-tapping screws and cover plates are coated with a waterproof membrane.
[0047] The presence of sealing gaskets and waterproof membranes helps to further improve the waterproof performance of the waterproof roof repair structure in pharmaceutical production workshops. It should be noted that the waterproof membrane can be formed by applying waterproof adhesive to the surface of self-tapping screws and nuts as well as the surface of the cover plate.
[0048] In an optional embodiment, the insulation layer 300 is a polyurethane insulation board.
[0049] Polyurethane has low thermal conductivity, is moisture-proof, waterproof, and has excellent fire resistance, flame retardancy, and high temperature resistance. Its closed-cell rate is as high as 90%, which can effectively prevent water seepage while keeping the room warm.
[0050] In an optional embodiment, the waterproof layer 400 includes a polyvinyl chloride film laid on the surface of the insulation layer 300.
[0051] In some embodiments of this utility model, the waterproof layer 400 is a waterproof membrane. Using a lighter material helps to reduce the roof load while improving the waterproof effect.
[0052] Polyvinyl chloride (PVC) membranes can be connected by heat bonding to obtain the required size waterproof roof repair structure for pharmaceutical production workshops. If the membrane breaks during use, it can be repaired by bonding with the same material, greatly reducing the difficulty of repair.
[0053] It should be noted that in this embodiment of the utility model, the waterproof layer 400 is made by covering the insulation layer 300 with a polyvinyl chloride film roll and fixing the edge of the waterproof layer 400 to the insulation layer 300. In some embodiments, some points in the middle of the waterproof layer 400 can also be selected to fix the waterproof layer 400 to the insulation layer 300.
[0054] In an optional embodiment, the waterproof smoothing layer 200 is a water-based polyurethane waterproof material coating layer.
[0055] Water-based polyurethane waterproof coatings are environmentally friendly high-molecular polymer elastic waterproof materials. The products are non-toxic and odorless, with good adhesion and impermeability, and are suitable for application on mortar, cement, and stone surfaces.
[0056] In an optional embodiment, the insulation layer 300 is composed of insulation boards spliced together, and an expansion gap of 1mm-2mm is provided between adjacent insulation boards.
[0057] In some alternative embodiments, the polyurethane insulation board can be 30mm or thicker. The presence of expansion gaps can prevent the polyurethane insulation board from arching due to mutual compression when it expands at excessively high temperatures.
[0058] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
